KEY MESSAGES

- Above normal temperatures and dry conditions are forecast into early next week, with a brief cool down possible toward the middle of the week.

SHORT TERM /THROUGH FRIDAY NIGHT/

Issued at 200 PM CDT Thu Oct 22 2026

Beautiful late October weather is expected to end the workweek with highs in the mid 70s on average across eastern Iowa and northwest Illinois. A 500mb ridge axis will remain situated over the Southern Plains to Mid/Upper Mississippi Valley region, bringing mainly clear skies and tranquil conditions to the local area. A tighter surface pressure gradient on Friday will result a little more wind (~10-15 mph) out of the south- southeast.

LONG TERM /SATURDAY THROUGH WEDNESDAY/

Issued at 200 PM CDT Thu Oct 22 2026

A tightening pressure gradient will remain across much of Iowa on Saturday as the surface cyclone over Canada deepens. As a result. Saturday will be breezier than Friday. In addition, this is expected to be yet another warm day, with highs once again in the mid to upper 70s as stronger mixing mixes down warmer temperatures. At least one more day of these well-above normal (near +15 degrees!) is in store on Sunday as the ridge axis translates eastward.

By Sunday night into Monday, a cool front associated with a surface cyclone over Canada will sag through the CWA. Model guidance remains split on timing for this front. The latest NBM has trended a little warmer, now showing mid 60s for highs in the far north to mid 70s far south. Models have also trended drier with the front keeping the better rain chances across western Iowa and into portions of Minnesota and the Dakotas, closer to the track of a mid-level wave.

Tuesday and beyond will bring occasional chances for rain and cooler temperatures to the area with highs in the 60s.

AVIATION /18Z TAFS THROUGH 18Z FRIDAY/

Issued at 1256 PM CDT Thu Oct 22 2026

VFR will prevail through the period with clear skies and light winds.
